Privacy is the default here, not the upsell. Pirai is for information and self-tracking only. It is not contraception, not a fertility treatment, and not a substitute for professional medical advice. Predictions are estimates based on the data you log. Always speak to a qualified clinician about symptoms or decisions concerning your health.
